Definitions

  • the present invention relates to a mold having a plurality of mold parts for producing cast parts in a casting machine, wherein the mold parts cooperate during the casting process, and a method for producing a corresponding casting mold.
  • a method for producing an injection mold in which a tool for producing an injection-molded part is produced in a negative mold. With the tool thus produced, a plastic part is then produced as a casting.
  • the negative mold consists of mineral casting or cement and serves as a simple casting mold for the production of the actual tool, which can then be finely processed.
  • a disadvantage of this production is that the negative mold can not absorb large loads and also allowed only very rough casts. Also, the injection mold thus produced can only be used for small and medium production quantities, and is mainly used for prototype production.
  • Object of the present invention is to provide a mold, which is very resistant and remains dimensionally stable even at high pressures and temperatures, making precision castings can be produced.
  • a casting mold according to the invention consists of a plurality of molded parts for producing cast parts in a casting machine.
  • the moldings work together during the casting process.
  • At least one is according to the invention the molded parts made at least partially of a high performance concrete.
  • High-performance concrete is understood as meaning a concrete with a compressive strength of more than 60 N / mm 2 .
  • High performance concrete has a high density and is commonly used in heavy duty construction.
  • high performance concretes have not yet been used. Both in direct contact with the casting to be produced as well as to support the shaping contour of the moldings, the use of high performance concrete has now been found to be extremely beneficial.
  • High performance concrete has properties that make the moldings sufficiently resistant to withstand high pressures in casting machines. While conventional concrete would be destroyed at the present pressures, at least with frequent use, the high-performance concrete is not only resistant, but also dimensionally accurate and can be used for high volumes. It is therefore possible that the high-performance concrete directly has the shape which the subsequent casting should have. This desired shape is maintained at the prevailing pressures and also at the appropriate temperatures in the allowable tolerances, so that the corresponding castings can be produced very precisely and also in large quantities.
  • the high-performance concrete of the molded part is milled and / or ground to obtain the desired negative mold for the casting.
  • a part is already coarsely poured into the desired shape and only the fine machining by means of milling and / or grinding takes place.
  • both the surface is improved and the exact shape obtained, which would not be easily achieved in a concrete formwork and the conventional casting process for the concrete body.
  • milling and / or grinding and complicated shapes of the molded part can be obtained. For example, tolerances of up to 1/10 mm can be achieved on a 5-axis milling machine.
  • a high performance concrete is used which is fiber reinforced.
  • the fibers blended in the high performance concrete add extra strength to make the moldings even more resistant. It is particularly advantageous in this case if small steel fibers are used in order not to damage the surface of the molded part when it is milled and / or ground.
  • the molded part is made of a low-shrinkage high-performance concrete, it can already be preformed very precisely in the concrete formwork. This reduces the effort for the mechanical processing of the molded part to bring it into the desired exact shape.
  • the molded part is biased in the longitudinal and / or transverse direction.
  • the molding is again significantly more stable and can also be used for very high pressures in the casting machine.
  • the molded part consists of a carrier part and a contour part.
  • the carrier part can be prefabricated and does not have to meet the very high precision requirements.
  • the contour judgment however, it is precisely manufactured to produce precise castings. Accordingly, the Kontgue is more complex to produce.
  • the processing of the contour part is easier to perform due to smaller size and material usage.
  • the contour part can be removed from the support member, for example, if it is damaged or should be replaced with a contours with another contour for the production of other castings.
  • the molded part consists partly of high-performance concrete and to another part of metal.
  • the carrier part consists of high-performance concrete, while the contour element itself consists entirely of metal.
  • moldings particularly inexpensive and accurate to produce which are made in the field of simpler contours of high-performance concrete and more complicated contours such as thin ribs are made of metal.
  • the metal can be screwed or glued to the concrete part.
  • the contour part and / or the insert are preferably made of a steel, in particular a high-quality steel or aluminum. The material to be chosen here depends on the casting process and the casting to be produced and the expected pressures and temperatures.
  • the molded part, in particular the contour part has a non-porous surface. This is especially achieved when a High performance concrete is used, which is largely pore-free pourable. Thus, it is possible that the concrete directly forms the contact with the casting, without pores of the concrete or other material, which was used for example for the contours, would find in the surface of the casting again.
  • the molded part, in particular the contour part is provided with a surface coating.
  • Such surface coatings may be, inter alia, paints or glass-hard glazes, which are melted, for example, for sealing.
  • the molded part, in particular the contours part is polished.
  • the polish produces optically smooth surfaces on the cast part, which also advantageously influence the demolding of the cast parts.
  • the molded part has a metal insert part which interacts with the high-performance concrete of the remaining molded part, more complicated shapes can be achieved for the cast part.
  • the metal inserts may be cast outside the molding itself or made in a conventional machining manner. With the molding they are then either cast with or releasably or permanently connected to the molding. In particular, thin ribs or other difficult to produce in concrete forms are thereby integrated with the molding.
  • the molded part in particular the carrier part, is cast together with functional elements such as holding grooves, guides and channels.
  • these functional elements do not have to be introduced into the molded part by drilling or milling.
  • You can be positioned with appropriate formwork and components already before casting the molding and are then in the desired Location arranged.
  • Functional elements may, for example, be retaining grooves with which the molded parts are held in the casting machine in order to be moved towards and away from each other. They can be produced by appropriate strips in the formwork.
  • Guides with which the mold parts are positioned to each other in the casting machine can be provided by sleeves and bolts.
  • Channels through which, for example, support part and contour part are screwed together can also be positioned by appropriate functional elements before casting as hoses, with which coolant is introduced into the mold.
  • the molded part can be cast in a reusable formwork, but it can also be advantageous if the molded part is poured into a box, which also serves as formwork for the high-performance concrete. In this way, the box contributes to a further strength of the concrete part, it can in this case a correspondingly less solid high-performance concrete are used, which can lead to cost savings under certain circumstances.
  • a plurality of molded parts cooperate during the casting process.
  • At least one of the moldings is at least partially made of a high performance concrete.
  • the high-performance concrete is poured into a formwork and cured in it.
  • a particularly high accuracy of the high-performance concrete is then, in particular after completion of a natural shrinkage process, milled and / or ground.
  • a very precise shape is obtained, which can produce a casting precisely and on the other hand ensures that the two moldings fit together exactly.
  • the high-performance concrete is mixed with fibers, in particular steel fibers, and then filled into the formwork.
  • the fibers cause one additional cohesion of the high performance concrete and thus increase the strength of the molded part.
  • the molded part is prestressed in the longitudinal and / or transverse direction, this too represents a measure to increase the strength of the molded part.
  • the molded part is produced in two parts. It consists of a support member and a contour part, wherein the support member can be made with a coarser tolerance and a different concrete mixture than the Kont culinary.
  • the contour part is advantageously produced with a high-performance concrete, which is very resistant and can also be worked very well and moreover a good surface structure is to be obtained.
  • the carrier part itself is designed in particular for receiving the contour part and essentially takes over the guidance of the molded parts and the reception of the molded parts in the casting machine and supports the contour judgment with regard to the expected forces during the casting process. Contouring can affect the entire casting mold or only parts of it. The remaining parts can then be shaped by the support member, especially if there are areas in the mold which must be shaped more accurately than other areas.
  • the contour part can be made for example of concrete, aluminum or steel and be processed with a milling cutter or grinder. If the contour part is produced by deformation, it is very easy to obtain, for example, by means of a sheet metal part. This correspondingly shaped sheet metal part is inserted into the support part and connected thereto.
  • the carrier part which carries the reshaped contour part supports the contour part so that it is resistant. The carrier part itself does not have to be made so exactly.
  • the molded part, in particular the contour part has a non-porous surface. This is possible if the molded part, in particular the contour part made of a non-porous concrete. The processing of the molding and the casting of the mold is thereby very accurately possible. Further processing of the surface of the molded part is then not necessary in every case.
  • the molded part, in particular the contour part is provided with a surface coating.
  • the surface coating consists of a lacquer or of another hard material or may also have a certain structure which is to be imaged in the casting.
  • the molded part, in particular the contour part is polished.
  • the molded part in particular the support part, is cast together with functional elements, such as retaining grooves, guides and channels.
  • the corresponding functional elements are positioned in the formwork for the molded part, as they are desired later. Further processing is then not or hardly required.

  • the mold 1 consists of two mold parts 2 and 2 ', which together are connected and work together.
  • a guide and centering of the mold parts 2, 2 ' takes place with sleeves 3 which are arranged in the molded part 2' and with bolts 4, which in turn are fastened in the lower molded part 2.
